Primary
| Measure | Time frame |
|---|---|
| Gait myoelectric indices (root mean square (RMS), median frequency (MF), integrated electromyography (iEMG), activation time of lower limb muscle groups during stance phase, co-activation ratio of muscle groups around the knee joint, etc., including quadriceps femoris, hamstrings, tibialis anterior, gastrocnemius, etc.);Full-length standing X-ray of the lower extremity, force line-related angles: Hip-Knee-Ankle Angle (HKA), Mechanical Axis Distal Femoral Lateral Angle (mMPTA), Distal Femoral Lateral Angle (LDFA), Joint Line Convergence Angle (JLCA).;Gait kinetic indices (e.g., joint three-dimensional torque peaks); | — |
